3D electromagnetic scanning system

Abstract

The invention discloses a 3D electromagnetic scanning system which can solve a problem of intuitive and visual representation of a three-dimensional spatial position relationship between a detection point and a measured object and spatial electromagnetic field distribution. The system comprises a control module, a 3D scanning module, a mobile scanning module, an electromagnetic probe and an electromagnetic signal receiving module. The control module acquires 3D contour information of a measured area and spatial position information of mark points from the 3D scanning module; the control moduleacquires position information of the electromagnetic probe on the mobile scanning module from the mobile scanning module; and the control module acquires scanning point electromagnetic signal frequency spectrum information received by the electromagnetic probe from an electromagnetic signal receiving module. And the control module converts the spatial position information of the mark points and the position information of the electromagnetic probe on the mobile scanning module to obtain a scanning point spatial position set of the electromagnetic probe, and finally fits the 3D contour information of the measured area, the scanning point spatial position set and the scanning point electromagnetic signal frequency spectrum information to output a 3D spatial electromagnetic distribution map.

Description

technical field [0001] The invention relates to the technical field of electromagnetic field intensity scanning, in particular to a 3D electromagnetic scanning system. Background technique [0002] The electromagnetic field intensity scan is used to obtain the electromagnetic field distribution in the space around the measured object, identify the strong electromagnetic field area, and then find the emission source that generates the strong electromagnetic field, so as to process the emission source, or take shielding measures to isolate the space radiation to reduce the space electromagnetic field intensity. [0003] The traditional electromagnetic field strength scanning is carried out by the tester holding the probe, and the automatic electromagnetic scanning system has emerged to solve the problems of poor accuracy and low test efficiency of traditional manual detection. There are two types of automated electromagnetic scanning systems: array scanning and mechanical scan...

Problems solved by technology

[0007] During the testing process of this method, two cameras need to be fixed at a fixed position to continuously shoot. During the testing process, it is necessary to avoid the blocking of the camera by the operation action, and the operation requirements are high. Secondly, the image recognition of the probe position is suitable for special configuration probes and probes with small color differences from the measured object. Recognition is difficult; in addition, the information of the measured object is displayed in a flat image, which cannot express the three-dimensional information such as the protrusions and depressions of the measured object, and cannot express the spatial position relationship between the test point and the surface of the measured object

[0008] It can be seen that in the prior art, the existing technical solutions for spatial three-dimensional electromagnetic scanning still have deficiencies in terms of ease of operation and visual display of results
